I got to shoot 30 rounds of Winchester 170 grain soft points through her yesterday. I had a few failures to chamber and I noticed copper smear on the edge of the feed ramp so a little polish is in order there. Also had a few stovepipes but I had the gas block turned down to 1 so that's probably my fault. The range I was at only goes to 30 yards so I left the scope at home and used the irons. All 30 rounds went into a half dollar sized hole so she is consistent. She has some rough edges but I think she'll come around with a little TLC.

Here's a pic, nothing fancy just a Century build on an ORF receiver.

My M76 was a little tight out of the box, but loosened up nicely with usage and is now very reliable.  Hopefully with, like you say, a little TLC she will be right as rain.



Lightening cuts on that receiver look very Wiselite-ish.

The guy I bought it from said it was ORF but I don't know enough about these to know for sure. I do remember reading that one of the vendors did very shallow cuts though. I'll spend some time getting her tweaked and try her out again.

How do you tell a Wiselite receiver from an ORF?

I'm not real familiar with ORF receivers, but I do know that the last generation of their M76 receivers had the oval lightening cuts that always looked very odd to me.



My M76 is built on a Wiselite receiver and it has the same shallow rectangular cuts that yours has.  Many Wiselite receivers also have a somewhat rough surface to them with machine marks visible.  If you have them, post up some close-up pics of both sides of the receiver.

Okay, mine has machining marks on the right side of the receiver. It starts where the stock/receiver join and runs down to the front edge of the lightening cut, the left side doesn't have any.
